hi there, sorry to bother you but i´m completely new at this , I´m using version 7.9.2 of Elastic,Kibana ,Logstash and Beats , i successuflly connected them to a MQQT broker ang got some information about camera analytics . I want to filter only the timestamp, from the message ,only the motion=0 or 1 and the first level of topic since this is the sender information , I managed to apply some filtering but i fail at the rest . i´m lost here ,can you help me? this is my pipeline.conf :

The # character at the beginning of a line indicates a comment. Use

# comments to describe your configuration.

input {  
beats {  
port =\> "5044"  
}  
}

# The filter part of this file is commented out to indicate that it is

# optional.

#filter {}  
filter {  
prune {  
whitelist\_names =\> ["message","@timestamp"]  
whitelist\_names =\> ["mqtt"]  
}  
}  
output {  
stdout { codec =\> rubydebug}  
elasticsearch {  
hosts =\> ["localhost:9200"]  
}  
}

Thank you in advance for the help!  
P.D.  
this is how the message looks like  
[mqtt|618x319](https://discuss.elastic.co/uploads/short-url/sr1SPUrdK504EGAoqdurDBEHOuK.jpeg)
